It's better you directly ask the UAE employer if they require a PCC from Qatar to process your UAE VISA.

If at all you require a PCC from Qatar, you can easily obtain it within 3 working days at a cost of 10 qr.
You just mention PCC required for UAE VISA while applying for the PCC.

You can also apply for a dual PCC, India & Qatar from the Indian embassy in Qatar in 1 working day at the cost of 120 qr.
